Be irkn m thatl, HENRY F. BECHMAN,

' of BattleCreek, in the county of Calhoun and State of Michigan, have inrented certain new and useful lmproven'ients in Means for Supporting \Veh-Ro'lls 'hile Being lfnwound;

and I herehy'declare that the followin is a full, clear, and exact description thereof, reterence being had to the accompanying drawings, which form part of this specification.

This invention relates to means for regulating the unwinding of wehs from rolls, particularly large'heary rolls of paper, such as areused in printing newspapers; and the ohjects of the invention are to provide a support for the weh-roll, so that no core or shaft need he placed therein or attached thereto, and which can lietlocated on thetloor-level, so that the roll otweb can he rolled into position thereon without the assistance of tackle, and wher'e'hy'the speed at which the web is unwoirnd from the roll and the tension on the web can he regulated to a nicetyand whereby the weh-roll can he easily shifted loi igltudinal'ly, so that the wch taken there from ill enter'the press or other rece'pti e device in proper position to he operated on therein. i j

The invention consists in thenorel construction and combinations of parts set forth in the claims following the detailed descripthereof.

tion of the devicef which is illustrated in the accompanying drawings, in which --Figure 1 is a plan view of the complete device with a weh-roll KY shown by dotted lines in position thereon. 'Fig. 2 is an end- YiQW Fig. "3 is an enlarged detalled scction of the roll-adjusting devices on line 3 3. Fig; 1, and Fig. 4 is an enlarged detail section on lin'e 4 4, Fig. 1. i

Two parallel'rollers A B. which may he of like length and size,are provided with gudgoons or journals (r l) at their ends hy which they are mounted in journal-hearings c c in the ends of an'ohlong frame or hase casting C, which. should he supported on a proper foundation over a shallow-pit adjacent to the 1 press or other machine to which the weh is to be fed and pretcrahly so that the upper parts ot-rolls A B project slightly ahove the floor-level in order that the weh-roll \Y may be easily rolled onto said rolls without lifting- Patented Sept.'4, 1906.

tacklehsaid weh-roll heiug supported thereon and therclatween, as shown in the drawings.

'The rollsA B should he slight ly longer than i the width of the widest weh the machine is intended to haudlcf In order to keep the weh-roll in position on the rolls A B, roll A is prorided with annular collars A A the former of which is prel'erahly loose, hut secured hy a set-screw u These collars A A are littcd against the ends of the weh-roll TV. as indicated in-tlie drawings after the latter is in place thereon and keep the weh-roll in position lougitiulinally of the rolls while it is heing unwound.

In order to shift the weh-roll longitudinally of the frame. so as to adjust the feed of the web laterally to the machine. one of the gudgeons (I of roll A is ntended through its heathy means of a screw or other suitahle device. Said cap int-loses the head rl" ot a screw through the aperture in the end oi the cap 15.

obvious that hy rotating said screw the roll A can heshift'cd longitudinally ol the lra!uo(.

(Not shown.) firdunu'lly the pull thereon, will he sullit'ient to unwind it: hutv itin any case it is desired to posit ively artu i ate the rolls A B to unwind lhe \Vtll power could he applied to shalt (l in any de ired i manner. pret'erahly hy gearing it to the ]H't.

bolt D, tapped through a licaringfin the BoltD also has a cylindric portion (/"passing As screw 1) is in alincmcnt with roll A it is and by reason of collars A A on roll A the on the web. caused hy the ma hino operating loo any unequal wear of its frictiona .a hand-screw J, tapped through a bracket j,

attached to the frame the inner end of said bolt iin )inging against the shoe H, as shown. The inc ination of slots 11 is calculated to iormit the shoe H to adjust itself to the surface of roll A and automatically com iensate for f surface It.

he operation of thedevice in unwinding aper is sufiicientlv evident from the foregomg description and drawings. While the device is particularly designed for unwinding: pur oses, it is obvious that it may be also uset for rewinding webs by sim ily applying power to shaft G to drive the roils in the desired direction. 'hen the rolls are driven by gearing, they should be rotated at a slivhtly less peripheral speed than the plateoy inders, so as to maintain aproper tension on the web.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is

1. In combination, a pair of rolls adapted to support a web-roll resting freely on and between them; with meansfor adjusting one of said rolls longitudinally and means thereby for keeping the web-rolf in position on and adjusting it with the adjustable roll.

2. In combination, a air of rolls adapted to. support a web-roll p aced loosely on and between them and to be rotated by the ull on the web; with an adjustable brake-s ioe bearing against the surface of one of said rolls to re ulate the unwinding and tension of the web I y retarding the rotation of the roll.

3. In combination, a air of rolls adapted to support a web-roll placed loosel on and between them; with an adjustab e brakeshoe bearing against the surface of one of said rolls, means for adjustin one of the rolls longitudinally, and "means or keeping the web-roll in osition on and adjusting it with the adjusta le roll.

4. In combination, a frame, a pair of rolls journaled therein, adapted to support aweb roll placed-loosely on and between them, a

ham -screw mounted on the frame, and :1 rotatable connection. between said screw and the adjacent roll whercli theroll can be adjusted longitudinally, and means for keeping the web-roll in position on. and adjusting it with the inljustable. roll, i

5. In combination, a pain of rolls adapted to support a web-roll placed loosely on and between them, means for keepingthe webroll ,in position longitudinally of the rolls, means for adjusting one of the rolls longitudinally, means for braking one of the rolls, and means for keeping); the web-roll in position on'and adjusting it with the adjustable roll, substantially as described.

j 6'. In combination, a frame. a pair of rolls mounted thereon, an adjlisting-screw mounted on the frame opposite the end of one roll, a rotatable connection;between said screw and the adjacent roll, collars on said roll, a brakeshoe beside one of the rolls, and means for adjusting its pressure against the ieriphery of said roll, substantially as described.

7. In combination, a frame, a pair of parallel intergeared rolls journaled therein, adapted to support a web-roll placed loosely on and between them, a hand-screw mounted on the frame opposite the end of the roll, and

a rotatable connection between said screw and the 'gudgeo'n of the adjacent roll, for the purpose specified.

8. In combination, a pair of parallel intergeared rolls, adapted to support a web-roll placed loosely on and between them, collars on one roll for keeping the web-roll in position longitudinally of the rolls, means for ad,- justing the collared roll longitudinally, and an ad'ustable brake-shoe controlling one of the roils, substantially as described.

9-. In combination, a frame, a pair of parallel roils mounted thereon, geari n51 between said rolls, an adjusting-screw mounted on the frame opposite the end of one roll, rotatabl'e connections between said screw and the ad.-

, 'acent roll, collars on said roll, an adjustable rake-plate beside one of the rolls, and means foradjustin its'pressure against the periphery ofisaid roll, substantially as described.

In testimony that I claim the foregoing as my own I aflix my signature in presence of two witnesses.
